Cooking frequency in Germany

The growing range of ready-to-cook and ready-to-eat foods (convenience foods) and opportunities to eat outside of the home is tending to reduce the number of fresh meals that people prepare themselves. However, people continue to place great importance on preparing their own meals from fresh foods, as this provides them with greater influence over the quality and composition of the food they eat. The German Health Interview and Examination Survey for Adults (DEGS1, 2008–2011) observed that 50.8% of adults aged between 18 and 79 (61.4% of all women and 40.2% of all men) prepare their meals daily or almost daily from fresh food. Moreover, women report less often that they never cook (2.9%) than men (16.1%) and older participants report far more often to cook daily or almost daily than younger participants. Finally, among both genders is a low level of employment associated with an increased cooking frequency.


Introduction
A balanced diet is important to maintain and improve health.Numerous studies show that diet plays a significant role in the development of many 'diseases of affluence' such as obesity and diabetes [1].Cooking habits may have a significant impact on people's diets [2].Therefore, an understanding of cooking habits in Germany could help develop approaches that would improve healthy nutrition promotion.Changes in society, to people's living conditions and developments in the food sector are bringing people to eat more often convenience products and foods outside of their home [3,4].In today's society, people expect food to be constantly available and easily accessible [5].However, such products significantly reduce the influence that consumers have over the quality and composition of the foods The proportion of women who cook every day or almost every day (61.4%) is much higher than the proportion of men who do so (40.2%).

Indicator
The German Health Interview and Examination Survey for Adults (DEGS1), which was conducted by the Robert Koch Institute between 2008 and 2011, gathered data on the frequency of cooking in people aged 18 to 79 [11].The study participants were asked to complete a self-administered food frequency questionnaire that included the following question: 'How many times per week do you prepare a hot meal (lunch or supper) yourself using basic ingredients/fresh foods?'The possible answers were grouped into three categories: 'every day/almost every day', '1 to 4 times a week', and 'never'.A total of 6,956 participants provided information about how often they cook, and this data was statistically analysed.The following describes cooking frequencies according to gender, age, education and employment status.
The information on educational status was categorised using the CASMIN index (Comparative Analysis of Social Mobility in Industrial Nations).This index reflects the various levels present within the education system and takes into account the differences between vocational training and general educational pathways [12].The participants' employment status at the time of the survey was grouped into four categories: 'full-time employment or training', 'part-time or marginal employment', 'unemployed or rarely in employment', and 'retired/pensioner'.

Reflection of the results
According to DEGS1, 50.8% of adults in Germany prepare their warm meals every day or almost every day from fresh, basic ingredients (Table 1).The proportion of women who report this is significantly higher (61.4%) than the proportion of men (40.2%).In contrast, men report significantly more often that they never cook (16.1%) than women (2.9%).Still, 35.6% of women and 43.7% of men prepare their meals at least 1 to 4 times a week.Similar differences in cooking behaviour between men and women were observed in a study conducted Older women and men are proportionately more likely to cook every day or almost every day than younger people.
on behalf of the Federal Ministry of Food and Agriculture [13].One reason for these gender-specific differences might be that women place greater emphasis on a healthy diet, and are more likely to be responsible for caring for the family [13,14].Alongside gender-specific differences, DEGS1 also demonstrates age-related differences in terms of cooking frequency.Participants in the oldest age group (65-79 years) cook the most often, with 81.9% of women and 60.6% of men in this age group cooking every day or almost every day.This confirms the widespread hypothesis that dietary and cooking behaviour differs considerably between the generations [15,16].The age-specific differences in cooking habits could be explained by the fact that older people tend to adhere to more traditional practices and probably also are more health conscious and consequently care more about their diet [10].Moreover, most people in this age group no longer have to work, which means that they have more time to cook their own food.In contrast, today's younger generation has grown up in a period offering a vast availability of diverse industrially processed convenience foods, and catering services [3,17].DEGS1 demonstrates that young women and men consume fast food particularly often compared with older people [18].
A low level of employment is also linked to a higher frequency of cooking (Figures 1 and 2).People who are unemployed, in marginal employment and pensioners cook significantly more often every day or almost every day than those who are in full-time employment.This could be because the majority of people in full-time employment have less time available during the day to cook for themselves.This could be reflected in a propensity to eat outside of the home far more often and in a preference for cooking on weekends [5].Among all age groups, there is a tendency, for both women and men with a low education level to cook more often every day or almost every day then those with a medium or higher level of education.However, these differences are not statistically significant (Table 2).Further targeted studies are needed to accurately assess cooking habits and their impact on dietary behaviour and health.The basic ingredients used and the way in which a meal is prepared may be more important for health than mere cooking frequency [19].Nevertheless, consumers who do cook have more influence over the type of food they eat and may find it easier to implement health recommendations, such as reducing salt levels.Moreover, people who regularly cook their own meals are more knowledgeable when it comes to handling food and often have better cooking skills.Another study observed that cooking abilities, particularly among people with lower socio-economic statuses, played a significant role in enabling these individuals to maintain a healthy diet [2].Measures aimed at increasing cooking frequency, therefore, could presumably play a role in improving the population's dietary habits.
